today, an historic achievement in space travel, nasa's rover curiosity touched down on mars in what scientists call a miracle of engineering. so just imagine the complications of actually bringing humans to mars. well, one south african-born billionaire is looking to do just that and more, as early as 2025. here's abc's david wright. >> reporter: astonishing new images of our closest neighbor in the solar system. sure, they're not quite the stuff of mission mars in 1968. not quite ray bradbury's "martian chronicles. the "either. >> this is a wonder drus moment.
>> reporter: and the most expensive mars mission to date, curiosity, a $2.5 billion robot, a size of a mini cooper that dropped down to the surface last night. >> this is all pretty much to scratch. >> reporter: here on earth, there are people already planning the logical next step. >> i think we'll be able to send the first in roughly 12 to 13 years in my estimate. >> reporter: meet elon musk, a high-tech executive who recently entered the space race. accomplishes a feat so difficult only the united states and the soviet union and china have ever done before. that is, developing a spacecraft capable of taking a man into orbit and returning him safely to earth. elon musk did it with rockets designed himself. what was inside?
>> well, our biggest was a wheel of cheese. >> reporter: musk has big mans for mars. not just taking people there, but making it possible for people to live there. >> we know it's possible to get there. the question is is a much more difficult one which is can we make a trip to mars affordable for the average person in the united states. >> reporter: what's affordable? >> well, bear in mind, you would be moving to mars, i think affordable, it has to be month more than $500,000. roughly, a middle class house in california. wow. >> that is a long way from actually making it occur, but i know it is possible. >> reporter: elon musk made his first billion creating paypal with his brother and in the process virtually created intern internet commerce. with his paypal proceeds he proceeded to found tesla motor cars and solar cities companies now at the cutting edge of renewable energy.
and he created spacex, a sprawling rocket design complex not far from l.a.x. in the most recent "ironman" movie, the lab served as the backdrop for billionaire tony stark's company, which is kind of appropriate. you're tony stark? >> in some respects, a bit like tony stark. >> reporter: do you fight crime in the off hours? >> not yet. >> reporter: no comment on that. musk even has one of the ireman costumes, a gift from the director. >> don't you want it to be that thing where it actually occurs and isn't always fiction? >> reporter: absolutely. luke at movies like "2001" and say what happened? >> exactly. >> reporter: he wants to do what governments do. >> we choose to go to the moon
and do other things not because they are easy, but because they are hard. >> reporter: musk must have been born after jfk was long gone, but he was inspired by jfk's vision. the idea of not only traveling to mars but colonizing mars, but isn't that a cool idea, but to you, it's a real possibility, something that you hope to see in your lifetime? >> i do, yeah. i'm confident that it can be done. it's the most difficult thing that humanity has ever tried to do. think about it, 4 billion years. it's been around for 4 billion years and all that time, it's been confined to one planet. that is a long time. now for the first time in almost 4 billion years, it's been possible -- very difficult, but possible for life to extend to another planet. and we should take advantage of that opportunity. >> five, four, three, two, one. >> reporter: i'm david wright for "nightline" in los angeles. >> to the red planet and beyond,
thanks to david wright. and just ahead, they compete in the olympics to be the best of the best. but how much is really fair game? ♪ [ male announcer ] start with a simple idea. think. drink coffee. hatch a design. kill the design. design something totally original. do it again. that's good. kick out the committees. call in the engineers. call in the car guys. call in the nerds. build a prototype. mold it. shape it. love it. give it 40 mpg. no, 41. give it a huge display. give it a starting price under 16 grand. take it to the car shows. get a celebrity endorser.
and now, for today's olympic results, my co-anchor bill weir joins us from london. bill. >> cynthia, i tell you, one way or another, one part of team usa figures out a way to thrill us on a daily basis. here in london dontonight, it w the women's soccer that beat the north american neighbors canada. but disappointment for gabby douglas finishing last on the uneven bar. she has one more shot at precious medal tomorrow on the balance beam. meanwhile, a lot of excitement
and a little bit of a suspicion bubbles up every time somebody puts a world beating number on the score bard in that stadium across the way. despite reinvigorated testing efforts, every game is haunted by doping standards past. this game's no exception. so we wonder how clean are the athletes of london 2012. and the answer, depends on who you ask. >> reporter: in the soft london afterglow, usain bolt's 100-meter win is being called the greatest race ever. >> usain bolt! >> reporter: but those with long memories may remember another sprint. when ben johnson beat carl lewis at the '88 games in seoul. the world swooned over the superhuman speed until three days later when he tested positive for steroids and was sent home in a cloud of scandal. and now 24 years later that final is considered the dirtiest
race in history, because as journalist richard moore points out in his new book, four other sprinters there that race went on to suffer doping standards of their own. so it wasn't just ben johnson? >> no. at the time, he was made a scapegoat. and i wanted to draw a distinction. he probably wasn't the only one. >> reporter: the man who ultimately won that race was carl lewis. after bolt's stunning appearance in beijing, he was the highest profile to raise suspicion, saying, quote, if you don't question bolt's times in a sport that has a reputation in the sport right now, you're a fool, period. but the doping control officer at the salt lake city games disagrees. >> usain bolt is a fantastic runner. when a run start to complain, there might be jealouscy.
>> reporter: when they criticized yang, the chinese were outraged. like bolt, they are athletes with clean records competing in sports with dirty pasts. so what has changed in 20-plus years. >> one thing that has changed, the independent body that the sport has always needed. and in those day, you had sports policing themselves. >> reporter: in addition to this "just say no" campaign, the ioc says a record 5,500 athletes have been tested. so far, they've only ejected five names. a albanian wrestler, a gymnast. >> you see it looks like that over there. >> reporter: chris cooper is a
bio chemistry professor at the university of essex. he believes 10% of olympians are doping. the hard part is figures out which ones. when you watch the game, you see an amazing performance, what goes through your mind? any suspicion? >> no, i enjoy the performance. i know people who say you must have been doping to get this time. so i think as spectators, we should not have that suspicion. >> reporter: and is there more scrutiny for the better athlete? people like in the usain bolt class, is it harder for him to dope than it would be for a discus thrower? >> i wouldn't say it's an unusual performance. it's a pattern of behavior. >> we have a very expensive drug testing program here in london for the olympic games. i wonder whether it's money well
spent with airport security checking everybody. how effective is that way of combatting terrorism. >> reporter: as for bolt, he's long maintained his skills come from his parents. his twitter bio, the most naturally gifted athlete the world has ever seen. bolt tweeted a shot of himself with the swedish hand ball team at 3:45 a.m. and he still has two races left to run. he is superhuman in many ways. cynthia, we'll have all the latest results for you. see you back here tomorrow. >> thanks, bill. and a final note tonight in june, we reported on the decades-long fight for health care for marine families sickened by contaminated water at ft. lejeune, north carolina. today, president obama granted them benefits for a former marine's daughter who died of cancer 25 years ago. thanks for watch.
